The inventiolirelates to -j certain improvements' in paper boxes, preferably including 1 a{ body portion ands telescopingcover, each [constructed from singlejbla'nks of; paper,

surfaces of the lining-of each vbeingprovided with: a coating: or finish that" will protect the contents of the box,'- m'oreparticularly metal ware, from corrosive :ortarnishing ef- 1 1 fects due to some 'ofthe constituents. of the" "fibers from which the box inaterialismade.

4G 1 Referring'to 'Fi .2 of'thedrawings, the

my blankforming the ody sectionand the telescoping cover is ofthe general'contour illustrated in said figure, itbeing understood that the cover forming blank is slightly larger 45 than the blank fromwhich thebodyportion L of the box is formed; The description of the 7 construction and mode of manipulatingthe body forming blank will, however, apply as well to the blank from. which the cover is su forme'd, so that it will unnecessary to de- 7 scribe the two elements separately.- Asindi- I a cated in" Fig. 2, 1 indicates that portion ofthe blank whichconstitutes the bottom of the j boxand 2and'3 represent the respectiveside f I walls withscore markings or creases between 60"" j the same and the bottom section" to facilitate folding: The? supplemental side sections 543 and 5' areformed. as extensionsot the side fmembers'2 and 3, respectively, with-scores or creases" between the members 'to;permit the supplemental s ide' members to be folded in-' wardto constitute 'part 'ofi thelining of the box. Formed as an extension of thesupp1e mental side 'memberflis a bottom liner section 6, which is of substantially the same size and-dimensions asthe section ,1, except for beveled sided notches 8, 8, which areexcised from. the ends of the section 6. As shown, the line'of juncture between the section 6 and the-supplemental side section l'is defined by a crease or scoring. The supplemental side 1 section 'j5 'is provided with an extension 7," "Fig.1 is a perspective" view ofthe comwhich'is" in the formofa relatively narrow l i V tongue, having beveled ends which register typical 'blank' with the overlying beveled edges of the notches 8,when the parts are in folded rela 7 tion, asher'einafter described.

'As indicated, the blank from which the, telescoping cover is made is, of; the same shape as that forming the body it-the box, bfit is I of'slightly larger dimensions and the blankv for the cover is provided with generally ellip' tics openings 26, V26 symmetrically disposedthe side and supplemental side members, so that; when these members are in folded'reiation, the openings forln; finger notches to facilitate the removal of the cover.
